System security for network resource access using cross firewall coded requests

ABSTRACT

According to one aspect, a method, system and technique for system security for network resource access using cross-firewall coded requests is disclosed. The system and technique includes a firewall, a first appliance device located behind the firewall, and a second appliance device located before the firewall. The second appliance device is configured to receive a data request, convert the data request into a coded request, and transmit the coded request to the first appliance device, and wherein the coded request corresponds to a specific type of data request. The first appliance device is configured to receive the coded request from the second appliance device and, if the coded request corresponds to one of a plurality of codes of a command list maintained by the first appliance device, process the data request.

EXAMINATION OF PRIOR ART

This patent is a continuation of the work that this inventor did when he filed provisional patent application 61/345,141.

Prior art requires a peering relationship between the server and the workstation that is requesting the information. This is efficient and conserves resources particularly on a server where shared resources are at a premium. This was particularly import in the very beginning of the computer industry because internal bus speeds were slow compared to more modern systems and the cost per cycle were extremely high. Now that costs per cycle have been significantly reduced we should look at alternate means of communicating so as to provide better means of secure information processing.

A direct peering relationship is not necessary and is one of the reasons why computer systems are vulnerable to outside entities. What this system does is allow for a peering relationship between the site providing the information on a peering server and it allows for a separate process that the peering server uses to get the required information. Using this set of processes allows for further separation of the secure information source from that of the server that provides the peering relationship. As a result the secure data is not at risk should an outside attacker gain access to the peering server. It allows for the disconnection of that outside attacker from the peering server and still allow for the possibility of continued service to others but as a last resort the peering server can be rebooted and since the peering server's configurations are located at a separate secure location any attackers code that may have been inserted is ignored.

Please note that this is not a firewall service because the firewall has to allow data flow so long as it meets a certain set of criteria within the data header. This is a major difference in that we are looking for a specific code in order to allow a data request to go through. This is also not a proxy server as a proxy server redirects traffic to another server, thus hiding the actual network addresses from a possible attacker. While this does redirect traffic we also monitor privileges of the peering server to make sure it is not under attack. We are also capable of removing any session that attempts to take over the proxy server and we can finally reboot the peering serve as well. None of these functions are part of a proxy server's function.

TECHNICAL FIELD

The present invention relates to providing system security to network access of applications and data. This happens through the use of currently available security system (firewalls, bastion routers etc.) and the addition of a set of appliances/servers. The purpose of the additional software and hardware allows for the screening of all requests for security information. As a result we end up with a whole security equation that prevents all external access “Hacking” into secure data systems and we can still allow access to the data to those users who need it. This patent also lends itself to being able to be ported over to a hardware/firmware design. If latency is an issue, it is expected that when the software migrates to using modern ASIC hardware technology, the added delay that the new systems impose will be reduced enough that it will be acceptable to the user community. A process has been designed to reduce latency issues in software designs.

BACKGROUND

There are 2 primary problems with secure information handling. The first is that the idea that most secure information released needs to be complete to be recognized as valid. This is not the case with complicated records. For example an individual wants to go to a car dealership to purchase a car on credit. It is thought that credit information required needs to be complete; this is false, what the credit officer needs to know is if the person before him/her is actually the person that is reflected on the credit report and what the credit score is as well as any comments on past credit history. Therefore the personal identification information like a driver's license number coupled with the last 4 digits of the SSN and the birth date will provide that proof of identification. The credit data is information that needs to be complete but the personal information that is utilized by thieves is still secure.

The second idea that is invalid is that the device that handles the secure information needs to be the same device that is used to access the information. This is particularly true of web access systems. What is needed is a type of version of the same system that humans utilize. The person responsible for securing the information is a different person who is responsible for the utilization of that same information. This system works well for people and will work well for computers. While the design philosophy that a user be allowed to directly access the information is more efficient (Please note the idea has driven the design of computer systems for over 40 years) it has not been successful in handling secure information.

There has been an attempt in doing this with the utilization of a “Secure” information vault on a server. The problem that faces security teams is that when hackers access a server, they always end up with the server's administrator privileges. This means that the “Secure” information vault now is controlled by the intruder. Once you loose the control, you loose the information. It is either compromised to outside sources or destroyed.

SUMMARY

What this patent does is allow the system that allows users of information to be separated from the systems that secure the information. We do this the same way we do it in a human system. This is a universal standard and has been codified through the use of SOX standards. Current SOX standards do not require electronic systems to be separated like human systems are because the current state-of-the-art does not allow for it.

For this method and system we utilize an electronic form, or digital code for a specific piece of secure information. By using a specific code we don't respond to other inquiries that would allow a secure storage system to be compromised. This specific code can be hidden within a larger digital word so as to escape detection if the information stream is intercepted.

The result of this is that when a hacker attacks a peering server and gains control over the server, the most information that the hacker can gain is the temporary access to the actual codes and not the information itself. Since we confirm, through other means, users privileges for access to information even if an outside person knows a current code for a limited amount of time (codes can change as frequently as the system is set up for) an unauthorized user cannot gain access to secure information.

The system is also set up so as to allow up to release certain portions of the data if that is what is required. Since we only release portions of the confidential information to the outside access points, an attacker who wishes to use an approved provider's credentials such as a loan approver, the attacker gains are never seen because we only let the portion of the data out that proves to the approver a specific point. Normally it is something like identification and/or a credit score. Of these only the credit data needs to be complete, no personal identification data needs to be complete. The attacker would have to enter the complete ID set, but the system does not need to provide the complete set back. For internal applications the same can also be done to all access points except from a trusted subnet. The trusted subnet is required for server and data maintenance and cannot be avoided. Please note that for external data access it is recommended that all access ports, except for the single port that is used to access the master device from the client device, be turned off. For internal devices there is more freedom in allowing more ports to be open, but the more that are open the greater chance that the secure system can be compromised.

This is not a firewall because a firewall has to allow for different types of data in a steady stream of communications traffic into out of a network. While that traffic stream needs to respond to specific rules, the firewall just reduces traffic it does not necessarily stop it. Therefore this device is really an appliance as it does a very specific thing very well, very fast. This also utilizes an encryption method that can be subjected to interception. Once the codes are known, then the information stream can be intercepted and read. This is the reason why client data should be encrypted utilizing one of several secure methods.

This is not a proxy server because proxy servers redirect traffic and hide the internal addresses to the outside world. While this patent does allow for the redirection of traffic, the processes of a proxy server are not monitored by intrusion detection devices and the proxy server is not set up to automatically “kill” an intrusive process.

Since the appliance monitors the program file permissions it is also able to handle intrusions faster and according to a specific policy. The most benign would just to notify network security, it would also be able to change the file permissions back to the way they were before an intrusion as well as close down the user process that caused the break down in security. If all else fails the external device could be reloaded and the server configurations would come from an internal master server.

DETAILED DESCRIPTION

We need to think of the security of electronic documents in the same way we think of the security of hard copy documents. Utilizing the state-of-the-art in network security we have bastions, these are like the outer perimeter of a military base. We have bastion routers these are like the gates at the front gate that you use a pass card to get through. We have proxy servers that act like a second type of fence as they hide the facility for the outside. This area between the bastion router and the firewall is often called the “DMZ,” can also contain public information servers or web servers. The last set of electronic barriers that is normally seen is a final set of firewalls between the DMZ and the internal network. At this point the company often separates internal data with internal company VLANs and often there is a set of firewalls leading to the most important company information.

With the current state-of-the-art what we really have is a set of “fences” to keep attackers out. We can keep people out but we really are not monitoring the “fences” to make sure that attackers are not going over, under or through them. This is different from our physical security because we have people who monitor the fences and if you try to come in over, through or under the fence they can catch you, wound you or worse. In electronic security you can think of information tunnels as a way of going over or under the fence. Our internal systems have a difficult time of handling these sorts of information streams because they are unable to look at the actual packets within the tunnel. They can only evaluate the tunnel packets and not the payload encapsulated within the tunnel itself. This kind of assault normally requires inside help but automated tools can set up tunnels as well. It just requires time to get your tool inside.

Physical security also has the added advantage of placing a person, a security clerk, between the requester of information and the information itself. This means that the individual requesting the data needs to know what it is that they want. The only inventory of the sensitive information is within the secure vault itself. If an electronic attacker gains access to a server they have access to that server's directory, the information inventory. The security clerk can also dictate the method of how the information is to be reviewed. People cannot just ask for the information and walk out again.

The current state-of-the-art has nothing like this, until now. With the incorporation of a MiMs (Man-in-the-Middle Set) we can do a couple of things. We still utilize our current tools suite. We still need our electronic “fences.” What we add is an electronic security clerk. Our clerk is capable of making sure that the file that is requested is the only file that is delivered. It is capable of making sure that the file directory is secure, and is also capable of monitoring its MiMs mate to make sure that its processes are not violated. Our electronic clerk can now “kill” attacking processes or even kill its MiMs mate if it is necessary to prevent an attacker from taking over and gaining access to the internal network.

MiMs units are installed in pairs the first one can be located forward of the firewall to the secure data. The proxy, web or peering servers are pointed to the first unit of the MiMs pair. The forward MiMs unit is also known as a sacrificial or client unit. Its processes are monitored by the second MiMs unit. The second MiMs unit makes sure that the internal processes of the first MiMs unit are not corrupted by an attacker it needs to be located behind the final firewall. Should the first MiMs detect an intrusion then it notifies the 2^(nd) MiMs unit and attempts to shut down the attacking process. If it fails then the second MiMs unit has the option of shutting down the attacking process and if that fails to reboot the first MiMs unit.

The first MiMs unit is responsible for accepting a data request and converting it into a MiMs relevant code it is also capable of monitoring proxy, web or peering servers. This code directly corresponds to a specific type of data request. The second MiMs listens for these specific requests and responds only to these requests. The second MiMs unit only responds to the specific coded requests from the first MiMs unit. These coded requests can be hidden within a larger 128 bit (or larger) word. If larger numbers of databases queries are required we can incorporate them as the code and/or encryption schema are not dependent upon specific bit sizes. The 128 bit size was chosen as a starter sequence as it was easier to explain in this document but we can expand the bit size. As the encryption schema is also a 1 time pad type of schema the same word does not have to be used consistently and as a result can be a very robust schema. When we get to the encryption process bit size choice can be explained. We are utilizing this encryption schema because we need to make sure that if the data stream is intercepted it cannot be easily read by a packet sniffer. The first MiMs can also be utilized to monitor the processes of a web or proxy server or could run as a client on a web or proxy server. If the first MiMs unit sees abnormalities on the web or proxy server it can also be set up to notify the web or proxy server to “kill” a specific process or even have the proxy or web server rebooted. The same processes that are used to monitor the first MiMs unit in the pair can also be utilized to monitor the proxy or web devices.

The biggest advantage to being able to monitor these devices is that it gives the system an ability to self monitor and recover from an attempted attack and still give the possibility of continued service. Utilizing the system as a web/proxy/peering server monitor and then as a MiMs monitor process provides us with a defense in depth against data access attacks.

The second MiMs unit accepts the code or the encoded sequence and parses out the encoded command. The second MIMs compares the encoded command to an internal command list. This list contains the specifics about what to do with the command. The database contains the address of the server the command needs to go to retrieve the information, or to the server that needs to receive the information string. If it is to receive a particular information string it also needs to know how long the string field is as well. If the data in that string violates the parameters the data is rejected.

STEP-BY-STEP PROCESS DESCRIPTION

FIG. 1 is a general process diagram—This is used to describe the general track that is happening with the system. When a peering server or a MiMs unit is first booted it gets its configuration from an internal source. “BootP” or “DHCP” type protocols already exist and are already standards they are needed to accomplish the mission of getting the booting configurations to the MiMs unit or Peering server but are not part of this patent. After the unit is booted a client request can be accepted by the device. The first MiMs unit establishes a relationship between all servers that it serves as welt as the Master Mims unit.

If it is a peering server then the server establishes a relationship to the user's workstation. The peering server then takes the request (note: the request can be an input or output request) and sends the request as well as user authorization information to the first MiMs unit. The Peering server then provides a countdown to the user as to what hurdles the request is going through prior to getting the data. This can be anything from the standard hourglass to an actual step-by-step count of where the data request is in the handling system.

The first MiMs unit accepts the request and goes through an initial authorization matching utilizing the company's authorization tools. The request is matches with the proper code and sent to the Master MiMs unit and is processed according to process. If there is a violation of the codes then it is possible that the information stream may have been intercepted and the request is handled by the violations process. The authorization process or the monitoring processes may issues then the packet is handed to the violation process as well.

The data is sent back to the Master MiMs unit and from there to the first MiMs unit and then on to the proxy, web or peering server and then it goes to the client. If there are more requests they are then sent back on to the first MiMs unit, if no more requests are needed the relationship between the user workstation and the web or peering server is shut down and the user session ends.

FIG. 2 is a General Flow Process diagram. Step 2—requires the management team to determine which files and directories need secure access and what type of access those files require. Step 4—has those permissions assigned to those files. Step 6—Are the files monitored for security? If no go to step 8; if yes go to step 9—step 8—Drop file from security monitoring process—step 9—send permissions to the master appliance/server database step 10—Is an encryption of security permissions required? If yes go to step 12; if no go to step 14—step 12—Encrypt permissions—step 14 collect and prepare permissions send—step 18—Data request is received by appliance—step 20—the item code is selected from the code database—step 22—Is this a data request or a data input? If input then go to step 24; if request go to step 30—step 24—Does the input data meet the length requirement rules? If yes go to step 30; if no go to step 26—step 26—Drop the request and processed to step 1206 the Violation process—step 30—for both the data request and the data input append the permissions to the request—step 32—send the request to the secure data appliance—step 34—Does the code match one of the internal codes of the master server? If yes go to step 38, if no go to step 1206 the Violation process—step 38 Is this an input or data request? If input go to step 42; if output go to step 40—step 40—get the data for the client and send it to him—step 42—store the client data—step 44—send the client back the data that was stored.

If yes proceed to step 110; if no proceed to 136—step 136—End of process—step 150—Determine maximum length of time before file and directory permissions are to be sent (in other words if the permissions were not sent by this time send them) as well as for code database swap—step 152—Set constant S=Maximum length of time (in sec) for permissions to be sent; set constant T=times in sec for code database change—provide these to File Process Monitoring step 400—step 154—define what directories and files need monitoring—step 156—Define what actions will be needed to take place if certain violations take place—provide to Violations process 1200—step 170—Will/are latency issues be a problem? If yes go to step 172; if no go to step 174—step 172—Latency issues require a shift to using the timer for permission monitoring as opposed to attaching the permissions to every request. Define constant L=length of time (in sec) between sending the permissions.
